### Game Theory

One, two, three. One, two, three. One, two, three. Oh, hi. My name is Yoav Shoham. I am a professor of computer science here at Stanford. My area is artificial intelligence, logic, game theory, electronic commerce. And I’d like to introduce my friend, Matt. Hi. I’m Matthew Jackson. I’m a professor of economics here at Stanford University and we’re here. My interests include game theory, political economy and the analysis of social and economic networks and we are here to tell you about an exciting new course that will be online, on game theory. And in terms of the coverage of this game theory course, it includes the games like we were just playing, rock paper scissors. Includes parlor games like Go, Chess, etc. But it also includes a number of really important examples of how people behave in the world today. And it covers basically the mathematics of rational interaction and also irrational interaction. So things like understanding how people will behave in an auction, how we understand how the markets like the New York Stock Exchange behave, how do political campaigns work, how do countries decide when to go to war. So, a whole series of very important applications. And that’s part of the reason it’s become such an important methodology in economics. Yoav, why is a computer scientists interested in game theory? Oh, I mean, today the interest in game theory in computer science is intense. And after all, how would we begin to analyze eBay or Peer to Peer networks or keyword auctions on Google, if we didn’t muddle the rationality and self interest of players, and so it comes very naturally to us now. So, let me tell you a little bit about the class and it’s structure. So, the course will have weekly lectures and the lectures will be divided into roughly 10-minute sections where you can answer some questions between the different sections. Those will be graded online and in real time, so you’ll get feedback about those. There will also be a final exam for the course. In terms of the subject matter, we’ll start by covering how you represent games, players, strategies. We’ll talk about the normal form, which is the canonical representation of the game. We will talk about extensive form games which allow for dynamics and for people to react to each other. We will talk about situations where there might be incomplete information. So, how did you bid at an auction when you’re bidding against somebody who might have different information from you? We will talk about games over time, repeated games over time. So there’s a whole series of the basic structures of games and analysis that we’ll cover. And there will also be a question board that you can interact with other students through so if you have questions about subject matter and so forth, you can get answered. I think that, in terms of prerequisites, we’re going to assume that people are familiar with basic calculus and also have some knowledge of probability so that you’ll know what, for instance, a conditional probability is, but we’re not going to assume any specific knowledge beyond that. So, it should be an exciting course. Very exciting. Really the first time such a course as game theory has been taught at such a grand scale really aimed at a very broad audience, not just specialists in economics or in computer science, but really anybody interested in strategic interaction with who is willing to embrace a basic mathematical approach. Very exciting. Probably also a little challenging given the broad interdisciplinary nature, in fact, you and I may find ourselves disagreeing at times. How are we gonna handle that? Can we agree to disagree? We’ll find out. So where were we, professor?

I don't know calculus =(

Awesome.

Also, I think it can occasionally be useful to sign-up for my free on-line class at learn-how-to-relax·org

@himzoidae

You people have to stop trying to bash people just to get thumbs up. QUIT ACTING LIKE DOUCHEBAGS!

@TmetheWise

You qualify too, sir! Just business, nothing personal.

@himzoidae How does that make sense?

@TmetheWise

Should everything make sense? Let go of the tangible mass of your mind, it is only an illusion.

I think this will suck, since the prerequisites are so low, but I'm really interested in the discussions related to chess mathematics. Behaviour in an auction is way off my list of interests.

@KirKanu This is not a class in combinatorial game theory; it's a class in classical strategic game theory. Why would the prerequisites be any higher than they are?

does anyone know what the weekly time commitment is for this?

thanks!

@mosyemessy you're welcome.

@eatmealiveplease for what?

There is an error in the CC:

It reads "muddle" where he clearly means "model" .. "the rationaliy"

Near 1:53

Game-theory related to ANY financial-aspect will soon be viewed as a criminal-activity; justly as crimes from the past were once known as legal; one such so-called legality of the past for example, was that of denying the right-to-vote to females. To-day, females are still denied even the most basic equalities, such as a simple title; for example, females-recruits in the USF are still called "Airman"; under the lens of reason, a crime also. Anything financial, not only the recent screwed-ups.

As for Economics as it is currently perceived, the only rational basic aspects associated to it, and thus circumstantial are the mathematical-models and the word decision; other words such as product, effect, favourable ambient, obstacle, efficiency etc,. are or may be attached to the decision. Speaking of decisions, History in one mode or another, whether the historian was a true or not, history I repeat, tells us that decisions have been as a generality, incorrect; turtle-like progress…

Could someone please explain why the preview lectures were taken offline?

I also only discovered the course after the registration ended, and now have no way of reviewing the content?

(Also; why is there a registration deadline? :S )

15 000 views : that's a classroom!

OMG when is this starting again?

I wanna sign up for this… 🙂

Now that's an introduction!

January 2013 (6 weeks long)

Will the videos be posted to youtube. I was unable to play them in the Spring Course.
